Truely offers several unlimited data eSIM plans for South Korea, with validity periods ranging from 1 day up to 30 days. Prices for these plans vary, starting at $5.52 USD for a 1‑day plan and extending to $74.93 USD for a 30‑day plan, while still providing unlimited data usage during the validity window.
Although the plans are advertised as unlimited, the provider notes that speeds may be throttled after heavy usage, reflecting a Fair Usage Policy that could reduce data rates once a certain threshold is reached. Travelers who are concerned about such potential speed restrictions should contact Truely directly to confirm whether a Fair Usage Policy applies and to learn the typical amount of data available at normal speed.
